POWER-TRANSMISSION DEVICE.

To all whom#may` concern.' V

` Be it known that We, LOUDOUN CAMPBELL and FRANK G. CAMPBELL, citizens of the United States of America, residing at Alex? i v andria, in the county of Alexandria and State of Virginia, have invented certain new and useful Improvements in -Power- Transmission Devices, of which the followin'isaspeciication. i l v y hls inventionrelates to atpower trans- ",mission mechanism and has for its object, e provision of an article of `this character `by Vwhich powerqmay be ltransmitted from th j machines.

l v, The Vinvention is particularly adapted for use in lclosinglarge valves `such as are cominonly employed in conjunction with the water mains oficities, though it is adapted 1 y after. set forth. l y.

` In the accompanyingjdrawmg, Fig. 1 is view partl Vin side` elevation and partly in section of? a `power transmiss1on`mechanism showingthe same used to close a large valve,- Fig. 2 is a plan vview of the struc- ;ture shwn'in Fig.'1, Fig.`-3 illustratesa flexible shaft 'hereinafter described, and Figs. 4`and 5 show modifications hereinafter described. l

i .I Like numerals designate .corresponding .'partsin all of the iiguresof the drawing. Referring to the drawing, itfwill -be seen that means are here provided for operating in water mainsy ofl cities. These valves .are gate valves and are of such size that the task of opening and closing themis avery slow and laborous one and it is the obJect of the invention shown in-these figures, to provide readyv means whereby the powerv plant et an automobile or motor truck .may be utilized f. Ito open or close these valves.

This shaft carriesagear wheel 11 that meshes with a pinion 12 and this latter pin-` ion has an angular extension 13 f or engagement with a key 14 of an operating rod 15.

through a pair of disks 16 and 17. The

flower of these disks, viz., 16 is stationary,

and rests upon the manhole vcover 18. This disk 1s provided with handles 19 for its easy manipulation; 'To prevent this disk from accidentally shifting its position, slotted plates 20 are 4secured to its under side bv bolts 21 and these plates may be adjusted rto iit the size of the particular manhole cover inconjunction with which the device isv to be used. The disk 16 has a neck exfor Ithe upper disk 17 and this upper disk carries upon its lower face, rollers 23 orlike anti-friction elements to adapt this upper disk to have rotative movement with relation to the lower disk. This upper disk -The oppositeend of the operating lever is pivoted at 30 to a bracket 3l carried by the lower disk. It is manifest, therefore, that if this handle 29 be pressed upon to force the movable member 25 of the friction clutch into engagement with the fixed member 24, any rotative motion of disk 17 will be imparted to the operatin rod-l5 and consequently to the valve stem to open or close the valve.

tation will be imparted to disk 17 to closel the valve, this being accomplished by pressing upon handle 29 to clutch the member 25 `to they member 24. That the operator may 1,35 and 36 of the disks 16 and 17. This locks vthese disks together. It is to be understood that this pin is only placed in position during the time the automobile is being run up'on disk 17 and this pin is for the purpose iof holding the upper disk stationary` at this time. After the automobile isproperly positioned, this pin is to be removed.

While the structure shown in Figs. 1 and 2 is well adapted for use in closing valves, it is apparent that the two horizontally arranged disks, the lower one fixed and the upper one vrotative with relation thereto and adapted to have the driving wheel of annutomobile run directly thereon, may be utilized for other purposes.

I Fig. 3 illustrates a lowei disk@ and an up-` per disk b, pivotally mounted at c with relation to`disk al Anti-friction devices such as- I' rollers vci providea rolling bearing for the upper disk u pon'the lower disk. The edge of disk b is formed as a bevel gear c which meshes with abevel pinion f. This pinion l is mounted upon a stub shaft g supported in a bracket h. The stub shaft carries a pulley i. 4It is apparent that by virtue of .this structure, an automobile maybe utilized to impart rotation to the pulley z' and to thereby drive any desired machine through the i medium ofa belt, not shown.

Fig. 3 illustrates an operating rod 15, the' lower end of which is in the form of a spiral or coil to render the lower endof this rod a flexible one. In this case, the key 14 is adaptedto engage with the angular member 13m-of avalve that is set ofi to one side of the manhole. i

The sti'iicture shown in Figs. 1 and 2 may likewise beiitilized to draw electric cables through conduits and in this case the rod .15-

- which in other respects corresponds to rod 4o' i spool 15.

15,*is provided upon its lower end with a It ,is apparent that upon taking a turn of the cableor wire around this spool,

i 'rotation of the spool vwill draw the wire or i cable steadily vthrough the conduit.

-solutely the We are aware of the fact 'that it has heretofore been proposed-to utilize they power plants of automobiles toactuate other. ina- `chines, but so far as we are aware we'are ab,-

first to utilize the power plant of a motortruck, such as are usually emlployed. by the water departments of cities,

and to i' provide connections between said 'Y truck and "a gate valve located in a man hole l .belowl the surface'of a street, wlievrebyto.

openor close said valve under the power4 of said truck.
